Photometric measurements using NIRI in the infrared, the Sloan Digital Sky Survey in the optical, and GALEX in the ultraviolet
Photometric measurements using NIRI in the infrared, the Sloan Digital Sky Survey in the optical, and GALEX in the ultraviolet compared to the best models of the star and the debris disk. The estimated size of the disk is ~190,000 kilometers. The disk is most apparent at the longer wavelengths (above 1 micron) that NIRI measures
